Detectives investigating alleged inappropriate payments to public officials have made their 30th arrest.

The 37-year-old woman, understood to be a journalist who works for News International, was arrested by appointment just after 9am on Friday at Bromley police station in south London by officers working on Operation Elveden, the Met investigation into allegations of inappropriate payments to police and other public officials.

Scotland Yard said the arrest came as a result of information passed to the police by News Corporation's management and standards committee.

The Met said in a statement: "The 37-year-old woman attended Bromley police station by appointment and was arrested on suspicion of conspiracy to corrupt under the Prevention of Corruption Act 1906, suspicion of conspiracy to cause misconduct in a public office, contrary to common law and suspicion of bribery, contrary to the Bribery Act 2010.

"Today's arrest is the result of information provided to police by News Corporation's management standards committee [MSC]. It relates to suspected payments to a public official and is not about seeking journalists to reveal confidential sources in relation to information that has been obtained legitimately."

Previous arrests as part of Operation Elveden have included 12 current and former Sun journalists after information passed by the MSC to Scotland Yard. All 12 are currently on bail.
